v v 1 Claim.

This application is a division of my patent application Serial No. 291,146, filed' August 21,

This invention relates to a paper containerv made or paper pulp or the like.

The principal object of my invention is to provide a paper pulp container with an integral bottom and side structure so constituted that it will have the necessary consistency and firmness relo M may be a: inch thick, thus providing a very quired to permanently maintain its shape and which will be practical for commercial use, and

' be suitable to hold liquids and sOIid ioods. An-

other object is to provide such a container that can be manuiactured at a low cost.

The foregoing and other obiects which will appear as the nature of the invention is better understood, may be accomplished by a construc tion such as is disclosed by the drawing and specification. The nature of the invention is such as to render it susceptible to changes and modifications, and, therefore, I am not to be limited to said disclosure; but am entitled to all such changes thereirom as fall within the scope of my claim. In the drawing:

Figure 1 is a front elevational view, partly broken away and partly in section, of a finished paper container. Figure 2 is a plan view oi said container and Figure 3 is a bottom view thereof.

so bottom structure being fiat and 01' a uniiorin As illustrated, my finished container R has an integral bottom and side structure.- Where the side structure M merses with the bottom structure N this intermediate portion U is preferably (c1. ass-as) arcuate in shape as'shown in Figure 1 of the drawins. Said bottom structure N is thinner than said side structure M and thinner than said intermediate portion U, and this thinness preferit ably results from compacting the material oi said bottom structure N so that it occupies less space than the material in said side structure M. For instance, said bottom structure N may be only %2 inch thick while said side structure firm and compact bottom, which constitutes the basic support 01 the remainder oi the container as well as its contents.

When desired my container R. may be fitted is with a metal liner L of aluminum or the like,

or it may be plated or treated with some substance or chemical composition it desired, to render it waterproof.

The apparatus and method used in making my :0 container are the subject matter of my pending patent application Serial 210,291,146.

What I claim is: A container made of paper pulp comprising an integral bottom and side structure, a portion oi as said structure extending arcuately between said top structure and said bottom structure, said bottom structure being thinner and the material forming it being more compacted than said side and arcuately extending structure, all of said thickness. and said side and arcuatelyextend- MYMOND E.
